Answer:
Step-by-step explanation:
‘a’ in this question is the slope of the line. Slope is (y2-y1)/(x2-x1) for any two points. We can see the line intersects the point (0,0) and (-10/9) so the slope is -10/9 which is less than -1 so
a<-1

Two different age groups were surveyed about the amount of time they spent on social media.
For b you had to add 25 and 35 together to make 60.
Divide 60 by 2 to get 30. 30 is the average between the two numbers. You then find the frequency of 30 using the graph. For the 12 year olds it is 40 and for the 18 year olds it is 60. Find the difference between these 2. So 60-40= 20
what is ask in the problem
The points (-16, 12) and (-29, 10) form a line segment.
Write down the midpoint of the line segment.
Midpoint Definition: The point where a line is perfectly split in half
Coordinates exist in the form of ( x, y )
Generally, you find the midpoint by adding up the two numbers and dividing the sum by 2.
In other words,
Midpoint = ( [tex]\frac{x1+x2}{2} , \frac{y1+y2}{2}[/tex] )
You should get ( -22.5, 11 ) as your answer.

The probability of a head is 0.27. The coin is thrown 200 times. Write an
estimate for the amount of tails
Answer:
The estimate for the amount of tails is 146.
Step-by-step explanation:
For each throw, there are only two possible outcomes. Either it is a head, or it is tails. Throws are independent. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
Can be approximated to a normal distribution, using the expected value and the standard deviation.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
The standard deviation of the binomial distribution is:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]
The probability of a head is 0.27.
This means that the probability of tails is [tex]p = 1 - 0.27 = 0.73[/tex]
The coin is thrown 200 times.
This means that [tex]n = 200[/tex]
Write an estimate for the amount of tails
This is the expected value, so:
[tex]E(X) = np = 200*0.73 = 146[/tex]
The estimate for the amount of tails is 146.

6x + 26 = 8x - 12 ( 1 - 3x )
6x + 26 = 8x - 12 + 36x
Doing like terms on one side,
6x -8x -36x = -12 -26
-38x = -38
x = -38 / -38
x = 1

Given that slope = -4 and a point (-2,5), write an equation in standard form
of the line.
Solve and check the equation.
x/9=x/10-4
Answer:
x = -360
Step-by-step explanation:
x/9 = x/10 - 4
=> x/9 - x/10 = -4
=> x/10 - x/9 = 4
=> 9x/90 - 10x/90 = 4
=> -x/90 = 4
=> -x = 90(4)
=> x = -360

An economist conducts a nationwide survey to study the financial perceptions of US adults. Specifically, he asks a random sample of 1,000 US adults: “Financially, are you doing OK or are you struggling to get by?” The results of the survey show that 829 of the 1,000 participants said they are doing OK.
(a) Construct a 95% confidence interval for the proportion of US adults who would say they are doing OK.
(b) Shortly thereafter, a similar study is conducted in Mexico with the intention of constructing a 95% confidence interval for the proportion of Mexican adults who would say they are doing OK. What is the smallest sample size that can be used to guarantee that the margin of error will be less than or equal to 0.01?
Answer:
a) (0.806, 0.852)
b)Margin of error ≤ 0.01
1.96*√{0.5*(1–0.5)/n} ≤ 0.01
√n ≥ 98
n ≥ 9604
• Smallest sample size = 9604

jordans dog weighs p pounds emmett's dog weighs 25% more than jordan's dog which expressions represent the weight in of emmett's dog? a.0.25p b.1.25p c. p + 0.25 d. p + 1.25 e. p + 0.25p. Select two answers.
Answer:
B
Step-by-step explanation:
I think because if it weighs 25% more, then Jordans dog is the "1" part and Emmetts dog is the .25 part.
Answer:
B, 1.25p
Step-by-step explanation:
Lets say that Jordan's dog is a certain weight making him 1, It says Emmett's dog weighs 25% more, so that would give us 1.25. Now the reason is that it's B instead of C is that we have a p next to our 1.25. This means that its 1.25 x p, p being your pounds. So if you were to understand this equation, it would be, 1.25 x pounds. Let's also remember 1 x 1 = 1. So 1 x 1.25 is 1.25. 1 times anything is going to be the same number.
A picture shows the net of the lateral surface of the cone. Which statement about this cone is NOT true?
Answer:
Area of the Net is incorrect
Step-by-step explanation:
Base Surface Area = π×12^2
= 452.38934211693 inches^2
Lateral Surface Area = π×12×√12^2 + 15^2
= 724.1762903163 inches^2
Total Surface Area = 1176.5656324332 inches^2
Help me please I need the answer for questions 9 part A and Part B
Answer:
Part A:
c = 4 + 1.50h
c = 1 + 3h
Part B:
2 hours
$7
Step-by-step explanation:
Part A:
Number of hours = h
Cost = c
Cost for Ice Dream:
c = 4 + 1.50h
Cost for Skating Paradise:
c = 1 + 3h
Part B:
Set the equation equal to each other and solve for h:
4 + 1.50h = 1 + 3h
Collect like terms
4 - 1 = -1.50h + 3h
3 = 1.50h
Divide both sides by 1.50
3/1.5 = h
2 = h
h = 2
The cost for both locations would be equivalent at 2 hours
✔️The cost is:
4 + 1.50h = 1 + 3h
4 + 1.50(2) = 1 + 3(2)
4 + 3 = 1 + 6
7 = 7
The cost is $7

Noah works at a concession stand selling bags of popcorn and cans of soda. A bag of popcorn costs $2.50 and a can of soda costs $1.50. One night, he notices that he sold a total of 300 items and collected a total of $522. Determine the system of equations that could be used to solve this problem, where x represents the number of bags of popcorn sold and y represents the number of cans of soda sold
Set up 2 equations:
Total items sold: x + y = 300
This gets rewritten as x = 300-y
The second equation is for total amount made:
2.50x + 1.50y = 522
Replace x in the 2nd equation with the value of x from the first one:
2.50(300-y) + 1.50y = 522
Simplify:
750 - 2.50y + 1.50y = 522
Combine like terms:
750 - y = 522
Subtract 750 from both sides:
-y = -228
Divide both sides by -1 ( to make y positive)
y = 228
Now replace y in the first equation to solve for x:
x+ 228 = 300
Subtract 228 from both sides:
x = 72
He sold 72 bags of popcorn and 228 sodas.
Marco is building with bricks. He needs 560 bricks total to build a wall, but only has 445. The price per 5 bricks is $25. How much money does Marco need for a total of 115 bricks?
Answer:
575$
Step-by-step explanation:
If each 5 bricks is 25$ and Marco already has 445 all he needs is 115 more bricks and 115 divided by 5 is 23 so 23 groups of 5 bricks and 23*25 is 575$
